MOLD-HANDLING- APPARATUS.

Application led August 14, 1922. vSerial No. 5781,688.

To all whom t may concern.'

Be it known that I, `Josnrn S. TINDALL, a citizen ci the United States of America, residing at Cedar Springs, in the county of Kent and citate of Michigam have invented certain new anduseful Improvements in Mold-Handling Apparatus; -and I do hereby declare the following to be a full, clear, and exact description of the invention, suoli as will enable others skilled in the art to which it appertains to make and use the same. l

,This invention relates to a novel and ei- 4iective apparatus for handling molds, particularly, burial Vault molds madefrom concrete usually. It is a primary object and purpose of the present invention to provide a construction by means of which burial vaults of concrete or like material may be readily made and handled with ease and acility. A further objectfoi the invention is to provide an apparatus of this character wherein the vault, after setting and hardening inthe form suiiiciently may be moved `out of the way to make room for the construction of others, the movement of or transportation ofthe heavy vault and the form in which it is made being very easily and expeditiously accomplished. A still further object is to make this apparatus y' economically, yet at thesame time, make it strong, serviceable and durable so -as .to be fully capable of withstanding any service to which it may be put.A These and various other objects and purposes not at this time speciiically stated, together with novel constructions for attaining the same will, appear fully as understanding of the invention is had from the following description, taken in connection with the accompanying drawings, in which- Fig. l is an elevation, with parts broken away and in section, of the apparatusconstructed in accordance with my invention.

Like reference characters refer to like parts in the diiierent figures of the drawings.

In the construction oi the apparatus, two

substantially semi-circular segments are provided, each made up oithree thicknesses orA lumber, the outer members 1 of whichA are longer than the inner member 2 whereby at each end of each segmenty a space or` recess is left between the ends of the two `outer members l. These segments on their linner sides at two opposed points-are cut stantially equal to the length of the vault member to be made and are secured in such position, relatively to each other by two members 4f of lumber seating in the notches `3 against the rhorizontal sides thereof and permanently attached to the segments ink any suitable manner, additional securing and strengthening members 5 being provided under the members 4 and at right angles thereto. In practice, I have made the construction of two-inch plank and the same works veryk satisfactorily, but it is evident `that the constructionis not necessarily made in this way and'maybe widely varied as -to materials used. On the members 5, I have pivotally connected levelling legs 6 which when turned down into operative position,'as shown in Figs. l, 2 and 3, keep the apparatus level and hold it againstroll ing movement on the segments.

Levelled in this manner, the vault form may be applied.v I have shown the same as comprising an outer metal box-like member,' `havinga -bottom 7 and vertical sides and ends 8, associated with which is an inverted smaller member oi like construction with a bottom 9 and vertical sides and ends 10. When. inverted and placed within the outer member of the vault form, the sides and ends 10 are spaced fromthe sidesand ends 8 of the outer member and the form is open at its upper side orthe reception oi cementitious vmaterial which may be entered into the space between said sides and ends and over the inverted bottom 9 of the inner or. core member of the Jform, whereby a burial vault 11 of cementitious material may be veasily made, it being understood that this. is one member only of the vault, two sub? stantially like members being required to complete the vault. It is to be further understood that the vault form shown is for illustra-tive purposes only, the specific forni and construction thereof being no part of the present invention.

The pouring of the cementitious material into the vault form takes place when the apparatus is assembled'a's shown in Fig. 3. After the concrete or like cementitious material has 4set sufiiciently, the remainder' of the apparatus is applied. This consists of `two like ksegments of substantially semicircular outline, also 'made of three thicknesses of material, two outer' pieces of lumber 12 and a middle thickness 13, at its ends being extended to provide tongues 14C' to enter the recesses between the ends of the outer side pieces 1 of the first described segments. These last segments are likewise formed with recesses 15 in opposed sides, similar in form to ,the notches 3 Jfirst described. These segments are'placed above the first segments, tongues lapassing into the recesses in the ends .of said first segments, it being evident that a circular wheel at each end of the form is't-hus made.

"The upper sides of the notches or recesses 15lie a' distance above the vault 11, and in practice, I place two boards or plank 16 lengthwise of the vault, one at `each side thereof, with the ends of the plank received in said notches 15. I may also place a cross yboard 17 over the ends of the boards 16, this not being at all essential except as a space filler. Wedges 18are then driven between the upper sides of the notches at 15 and the cross boards 17, previous to which, however, the segments have been securely7 connected togethery in some manner, as for instance by driving wedging keys 19 through openings 2O made in conjunction with each other in y.the end portions ofthe outer sides 1 of the first segments and in the tongues 14, as shown. Additional wedges may be used to secure the vault form against movement with respect to the apparatus, whereupon the entire structure may be rolled on the wheels made in effect by the joining of the segments, toany desired place in the factory and away from the place where the concrete is poured into the form. This gets the* apparatus out of the way and leaves space for the making of another vault with like apparatus.

If the cementitious material has hardened and set sufliciently, the apparatus may be removed therefrom. In fact it is ready for ref moval at once as the concrete must have been boards 16, and if necessary, wedges are driven between the upper sides of said supportsr and the boards. The wedges 18 are then driven out. freeing the boards 17 which are removed. Keys 19 are driven out and the upper structure lifted up in any desired manner and carried back to the place where the new vault is to be made. The under segments are free and can be removed at once. Thereafter. it is only necessary to remove the vault form, which in commercial vault yform is very easily done, the vault being left on the supports 21 and the entire apparatus, excepting the boards 16, being ready for reuse.

This construction is practical and has been used with exceptionally satisfactory results. Ease in handling, capability of ready movement thereof to any place where the completed vault is to be left, ready and quick setting up for working operations and general simplicity and durability of the apparatus coinbine to make the apparatus one of great value. One feature of the apparatus is that the height at which the work is done is convenient in every respect. lt is understood that the construction is capable of considerable variation without in any respect changing the nature of the invention, and l do not consider the specific'showing made to. be inianysense limiting the invention thereto. The invention is defined in the claims appended hereto and all forms of construction coming within their scope are to Jbe consideredas comprehended by the invention.

l claim:
